At a first glance, the Arctic P12 Lineup may be overwhelming, but we will try to make it as clear as possible. Arctic's Lineup of 120mm Case Fans is grouped into 2 big Product Lines, the P12 Series & the F12 Series. Additionally, they did manage to keep the noise level pretty low, and even be "un-noticeable" in the lower 50%s of their PWM Speed.

While the F12 Series is Airflow optimized, it spins way slower (1350 RPM) and produces way less air pressure, but can push a lot of air for such a slow-spinning fan. So overall, on the performance side, the Arctic P12's are an excellent choice for anybody that does not want any unnecessary RGB features in their build. While we installed the P12's we did notice a small thing that could have been better thought through. Even though the PST (Daisy-Chain) system was very useful while mounting them, the attached extra wire was way too short.If you want to control several fans from one unique motherboard header, you can use PWM splitter cables such as the ARCTIC PST Cable rev2 . We however recommend to limit the number of fans per header to 5 as the current may be limited to 1.0 A per header (please refer to your motherboard manual). As we used the P12 PWM in their "PST" Version, we were able to make use of their "Power Sharing Technology". This PST Plug basically adds an additional 3-Pin Output to the cable of Each Fan.

ARCTIC P12 Slim PWM PST - 120 mm Case Fan with PWM Sharing
P12 / F12 PWM PST CO => Has a PWM Connection + Daisy Chain Connection + Build for Constant Operation While Benchmarking, they managed to outperform everything we own under full load and managed to keep a very good position while letting the Fans spin slower. With 62°C on the CPU and 43.5 dbA, the P12 even managed to outrank the Noctua NF-F12 in both metrics, even though the Noctua's are almost double the price. While we attached the first Fan to the PWM header on the Mainboard, the short PST extension forced us to also rout the Cable of every other fan to the front of the case.
By doing so, we can use the CPU Temperature as an accurate measurement as the CPU temp now only relies on the Air that the Case Fans are pushing into the Case. Even though we were perplexed that they did not manage to repeat their results, they performed excellently with 83°C on the CPU. To our delightful surprise, the Arctic P12 PWM managed to beat absolutely every other Case Fan that we own. Because the P12's are aimed at the Performance-only market, we will also cease to let their design affect our Review. After letting Heavyload grill the CPU, we came to the following results while the Fans were spinning at 100% PWM.
